Protein Boom Reaches Older Adults as Experts Highlight Eggs, Yogurt and Microalgae—and Warn Against Excess

Overview

• Guidelines cited in the reports set daily targets at roughly 0.8–1.0 g/kg for healthy adults, about 1.2 g/kg for older adults, and 1.4–2.0 g/kg for athletes.
• Specialists emphasize that eating more protein than needed does not increase hypertrophy, with surplus oxidized or stored and the remainder excreted by the kidneys, potentially increasing renal load.
• Practical options for adults over 50 include eggs with all essential amino acids, yogurt rich in leucine and micronutrients, and microalgae such as spirulina, which can reach up to 70% protein by dry weight.
• Market data reported by O Globo show protein products moving into the mainstream, with supplements projected to top US$3 million in 2026, high daily use among health‑conscious consumers, strong ready‑to‑drink sales, and rapid growth of plant‑based options.
• G1’s coverage underscores that whole foods generally meet needs, advises spreading protein across meals, and notes higher risk from high‑protein diets for people with impaired kidney function.
